OCZ Vector 256GB SSD Review

IOMeter is another open source synthetic benchmarking tool which is an I/O subsystem measurement and characterization tool for single and clustered systems, originally developed by Intel Corporation who ultimately discontinued their work on the software which today is a free and open source application.

All users who stayed in touch with SSD drive technologies for the past couple of years know that Sandforce-based controllers dominated the 4K aligned benchmark of the IOMeter for years, as the compression algorithms which these controllers were based upon provided the best possible setting for this particular type of performance. As such, these drives delivered unnaturally high performance figures if a 4K aligned write test was run, yet the performance would drop tenfold during mixed and random tests. This is not the case with the Vector, which reached over 86 thousand I/Os per second in the 4K aligned test and also over 36.1 thousand I/Os per second during our mixed/random stress test.

SiSoft Sandra is a very popular software suite which can also be used as a synthetic all-around benchmarking tool. We are using two of the suite’s tests in our article, the File Systems benchmark and the Physical Disks Benchmark.

Most SSD drives that we have tested to this date failed to meet their specified performance figures in this test and the Vector is no exception, with the drive unable to reach a read speed of 550MB/s when tested as either a physical disk or as a NTFS formatted file system. On the other hand, Sandra’s read test results were very close to the maximum speed of the Vector, which is more than what we can say for most of the drive’s we have previously tested.
